storage_path -- absolute path to the top level directory which will contain
collections and resources
enable_lock -- if True, thread locking will be enabled during write operations
Overrides: object.__init__

shutdown(self)

source code  

Shutdown the subversion storage.
Does nothing effectively.
Overrides: Storage.shutdown

create_container(self, collection_name)

source code  

Creates a subdirectory within the storage directory
If it already exists does nothing. 

Keyword argument
collection_name -- name of the directory to create
Overrides: Storage.create_container

path(self, *args, **kwargs)

source code  

Returns the full path as a string of the resource
relative to the storage directory
Overrides: Storage.path

get_content(self, path)

source code  

Returns the content as a string of the resource found at 'path'.

Keyword arguments
path -- Path to the resource as returned by get_path
Overrides: Storage.get_content

get_meta_data(self, path)

source code  

Returns the content as a string of the resource found at 'path'.

content -- data as a string object
Overrides: Storage.put_content

put_meta_data(self, path, content, **kwargs)

source code  

Set the content at 'path' of the resource.

Keyword arguments
path -- Path to the resource as returned by get_path
content -- data as a string object
Overrides: Storage.put_meta_data

remove_content(self, path)

source code  

Remove the resource at 'path'

Keyword arguments
path -- Path to the resource as returned by get_path
Overrides: Storage.remove_content

remove_meta_data(self, path)

source code  

Remove the resource at 'path'

Keyword arguments
path -- Path to the resource as returned by get_path
Overrides: Storage.remove_meta_data

persist(self, *args, **kwargs)

source code  

Does nothing in the filesystem storage
Overrides: Storage.persist

exists(self, path)

source code  

Returns True if the resource at 'path' exists. False otherwise.
